@sineverba Many thanks to your hint. I do same everything starts working perfectly. No can use raspi serial nrf and not need to but not necessary Arduino nano to do gateway things.
Many thanks one more time.
This kind configure i put, everything works now ok. Tx rx and er led not work, but i can live with that 
./configure --my-transport=nrf24 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020 --my-transport=nrf24 --my-rf24-irq-pin=15 --my-rf24-channel=108 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18
Can someone tell why mysensors sketch take so much size on program memory. And i but debug // out commented first row and after that still printing serial monitor.
Here my code now. Can i do simpler that code because i know i use 3-5 ds1820 sensors not need to scan everytime what sensors there are and now they are harder rename.
Try to search some examples, but almost all use this ds1820 example code. I think code is more and more simpler if just do 3pcs ds1820 sensors and name that temps allready with some name. After that see directly on Domoticz what sensor is what.
Everyhints with this is ok, that works ok right now with this example code, but code is quite big (big sketch) and have that sensor scan system what i not needed.
What i can do that 30000ms sleep, if i but relay and switch systems in this same node.
Only edit is now couple rows code to use my oled display to show one ds1820 sensor temp. I understand that do this sketch little bit bigger, but sketch is quite big before that oled display.

* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.
